Dr. Dennis Gross Skincare Age Erase Recovery Mask ($48 for six, dgskincare.com) works its magic in two steps. You start by applying the clear cream in the first packet—it contains a high concentration of hydrating hyaluronic acid and ten antioxidants (including vitamins A, C, and E, and soybean extract) to fight damaging free radicals. Then apply the self-heating clay—to open pores and allow the cream's nourishing ingredients to deeply penetrate skin. After ten minutes, remove any residue with a washcloth.
